A rotatable Maten l is journaled in the emvls :mgl of u platen framen which also eouiprises a paper-shelf 5 connecting the eucls of the frame. said frame being shiftable' up und down in the traveling; carriage frame.. 'A roller 7. moimteul on the front rail (lot the Carriage frame, ti'ziveis on a horizontal rod S secured inthe stationary' frame 9 of themaehiue. The carriage is also supported anni `guided on n stationary rail. 10.

rifhe line-speee mechanism comprises a bell ero-ultieme il pivoted at 12 and having an arm i3 which ectuatesa slide bar 1`4" to which ispiv'oted :1 dog'l having a tooth 16 to engage n line-space wheel 17 secured to vthe platenV axle. A returning spring 145 4is connected to the slide bnr 14 and platen frame. A, spriugpressed detent 18 holds the platen in operated'position. The usual right and left-hand margin stops are provided. -Ag stop 20 controlling the left-hand mai-giri of the Work sheet Y i,-; 'slifl,eb ly mounted, -fo`1 the rod .8 and e parallel rod 21. Pivpted' to the stop 20 is a 'dogg 22 acljustubly held by rack teeth 23 formed on the rod 8. The dog 22 may be lifted froml its rack hyrqeans of e ne'er "piece-'242 to'permitedjust'met ofthe stop.

The rl holland margin et' the work sheetis control ed by i Stop Q5 'slidahly mounted on the rod 91 and @arri/ing a do;r which coperates with rack teeth 26 'formed on a bar 27, the dog being; releasable by means of a finger piece 28 to permit adjustment of the stop. The bar 27 is provided :it its ends with forwardly-cxtending,Y ears 29 i(.lurnahal on the rod 2l, whereby the bar 2'? ie permitted to oscillate about the. rod .21 a tulerum. A depending arm 30, secured to the I rack bar QT, carries :it its lower end a plvoted wiper 3l whieh works on a mun ein-tace 32 of a lever 33, carrying a hummer f5-l of a bell Projecting forwzufdly from the front rail 6 of the carriage traine is au :1l-ni 3G adapted to strike a cani Il? rari-led hv the stop 25, thereby deprer'f'sin'g the har :2i which swings the arm forwardly and ringe the bell. The rack har 27 may he returned bv a spring 38. The parts thurs fer deeerihed nmv be of usual construction as found in the commercial Underwood typewriting nnuflnnr.

The gage controlling the :n.itmmtie signal at the conipletion of the writing et a work sheet, comprises a, rack har l0 slidahly mounted on the `front rail of the carriage. This rack bar has substantially the shape ot an I-beam in cross sect-ion and comprises an upper horizontal flange 4l and a lower hori zent-al flange 42 connected by a vertical wel.;

,43. The rear extension on the flange 4l has cutaway portions to form a series of ratchet teeth 44. Rack teeth 4:5 are likewise formed on the rear extension of the lower flange Depending rack teeth 4 6 are also formed on the lower flange. The rack is guided livrtween the carriage rail f5 and a. verticallydisposed plat/e e7 secured to the rear .lace of said rail. Said 'plate is formed. at itel upper edge with a flangeoverhanging the lower flange of the ruck bar. Guide plates; 48 Secured to the upper face of the rail also overhang the lower flange 42 of the rack bar. The plate l? is forrned with de pending and torwardly-projeeting arms 4S) in which are threaded pivot bolts 50 having conical ends :forming adjustable cone hearings for e detenty lever 5l A detent. roller 52 carried by said lever seats between the rae-lr teeth 45 to hold the rack har. .lhe detent 'is held in position by a spring 55B.

The rack harisrnoved forwardly hy means of an operating dog' or lever 54: slidahlv and pirotallv mounted on the carriage rail 6 by means of a. screw 55 extending through a slot 56 in the lever :1nd threaded into the rail 6. The longitiidinal movement of the lever 5ft is limitedhy stops 57 and 58, adjustahly se` cured to thelerer by screws 55) and il() respectively. extending through slots in said stops and threaded into the lever. A limited pivotal movement of the lever is provided by a widened slot 6l, through which extends a mariee to reet on the erin 49 and limit the down-v ward movement of the end of the dog.,

:Secured to the luie-space lever 1 1 is an A.lu-in 63 which, when the lincfspace lever is actuated, strikes a cam tiet on the depending end of the lever 54. The n'iovexnent of the arm 63 is vin a horizontal direction sind when it strikes the rain surface 64 it swings the dog 5ft about its pivot and brings a tooth on the end. of the dog upward against the rack 4C. EL spring G6 connected :it itsiends t@ the piif'oted dog and carriage trarne7 has .ii'icient tension to prevent endwise movement o? the dog' while it is being swung up lo engage the rack bar, After this swinging movement oflthe dog.. the continued Inovement oit' the afin 63 carries the dog and' rack har iornard the distance between two adje-- rent teeth 46, when the morement iserrested hv the'lerer- 11 Astriking e stop. 67.

The parts are thus brought to the position v eliown in Fi 4. During' the forward movement of the dog a linger (i8 thereon engages behind the detent roller or an antiretion roller G9 below Said detent roller, and cams the latter outwardly to permit, free movement of the rack. Vlien the line-space lever itis released, the dog; .is returned by the epriiig` 66 intoA position 'to engege the next succeeding; toothof: the rack bei' when again operated.V ln thiS manner the 4rnelr har is fed forwardly one step at eaijfhioperation of' the line-Space lever until. the'raclr. teeth 45 paese bevond the det-ent 52; Vhen. this taires place the detent is carried inwtirdljfto, the position shown in ligf.' 7 whereby a tail ZG or' the detent lever iseanee'dto Strike a rearwardlv )ro'ectin 1 ledfre or tlanee 7l on the.

."u adjustable stop on the bnr 10 eem` prizes e spring-onerntedlatch 73 having e nose 74 to enter between any two'adjacent teeth lel of the rack and hold the ,Stop in adhasted position. A fixed sten' 75 formed h v a y'lrojection of the plate 'llies in the nath of the adjustable etop.- .vertical flange "(6 on the adjustable stop forms a. ting-er piece vfor returning the reel; at the time the work Sheet 'placed in the ma vhine, The adjustable stopl is placed at a dis-teure frorn'the left-hand end of the raek (Fie. f2) eorresminding tothe lnumber of lines it is desired to write ,on the Work' sheet. When the 'latter-is nlaeed in the machine. the rack bar is moved the left, to bring the sten thereon zig-einst the tixed'stop 75';

Ae the paper is fed 'forward through the machine by the operation of theline-. ;;niee

lever, the rack Ll() is m'oved to the right and aoy lOl)

ioy

at the completion of the writing on the work sheet automatically rings the bell, as hereinbefore explained. lfVhen a dilerent sized sheet is placed in the machine, or if it is desired to vary the width of the lower margin, the stop is adjusted along the rack, the direction and the distance corresponding to the desired change .in the number ofilines.

The rack bar is preferably provided,v withl scale markin s 77 to assist. in quickly and accurately a justing the stop. A finger piece 78 on the detent lever 51 provides a convenient means for operating said lever by hand.

When it is not. desired to use the signal device, the adjustable stop is moved to the right-hand end of the rack bar (Fig. 2) and the latch 73 is engaged in a notch T9. The rack bar is then moved to the left to bring the fixed and-movable stops together. In such position, the detent lever 51 is held up so that it will not interfere with the oscil- I lation of therack bar 27 in the usual way to give a signal'at the 'end of each line of Writing. The line-space lever cannotnow operate the rack because the tooth of the operating dog' is beyond the end of the rack 46,

Variations may be resorted to Within the scope of the invention, and portions of the' improvements may be used Without others."
